What is a walk-in bathtub and why is it ideal for seniors?

A walk-in bathtub has an opening door, a low step-over entry and usually a built-in seat. It can make seated bathing easier for someone who finds a conventional high-sided tub difficult to use. Soaking models are available alongside tubs with air jets, water jets and other comfort options. The best choice depends on the user's mobility, bathroom space and budget. Most walk-in tubs must fill and drain while the user remains inside.
